Peihan Miao 缪沛晗

I am an Assistant Professor in the Department of Computer Science at Brown University. I am honored to be part of Brown's Theory Group.

I received my Ph.D. from UC Berkeley in 2019 under the supervision of Sanjam Garg and my BS degree from ACM Honors Class at Shanghai Jiao Tong University. Here is my CV.

My research interests lie broadly in cryptography and security, with a focus on secure multi-party computation (both theoretical and applied). My research is supported by the NSF SaTC award, Meta award, and DSI Seed Grant.

I am looking for motivated students and postdocs. Please send me an email if you are interested in working with me.
